Change in physico-mechanical and thermal properties of polyamide / silica nanocomposite film

By S. S. Bhattacharya and S. B. Chaudhari

Abstract

Abstract:- In this work, polyamide (PA)/silica nanocomposite films prepared by dissolution method of composite mixing were investigated. The morphology of nanocomposite films were characterized using scanning electron microscope (SEM), reveals that nano silica powder were uniformly dispersed on PA silica nanocomposite film. Chemical composition of film was confirmed by Fourier transform infrared spectroscopy (FTIR). The nanocomposite films obtained from dissolution mixing exhibited an increasing tensile strength with an increase in silica content. Thermal behavior of the film were evaluated by DSC, revels that incorporation of silica nano particles in PA film increased the enthalpy (ΔH) value of the film compared to the pure polyamide film.
